Benefits Of CLA Supplements

CLA has great benefits to training and performance, as well as health and wellness and is considered to be a very helpful supplement by many. Knowing the benefits surrounding this supplement can prove most effective as you seek the best for your overall health and wellness.

Benefits of CLA include:

  • Aid in weight loss and fat burn: CLA works to suppress your appetite and increase energy expenditure, using stored fat for energy, thus aiding in fat loss (2,3). It can also increase fat burning for that vital boost and inhibit fat production to keep that lean physique.
  • Helps keep lean muscle: By working to shed fat and not use that lean muscle for fuel, you can keep that hard earned muscle for a desired aesthetic (4).
  • Pure and bioavailable: Made with pure ingredients, your body reacts positively to CLA and it can be absorbed quickly and effectively into your body for optimal benefits.
  • Natural supplement: Made with natural ingredients, these supplements typically do not contain natural or artificial stimulants to ruin a great product.

Safety & Effectiveness

On the whole, CLA is a safe supplement to take. Some side effects of taking too much include digestive problems, nausea, constipation, stomach pain, and indigestion, but to avoid these, it is best to always read the label and talk with a medical expert if you have questions or concerns. While CLA tends to be very effective in terms of its benefits, some have found that it didn’t change their body fat mass or physical performance all that much.
